This thread has gotten a lot of attention, and that's probably expected since our old Birds have a tendancy to run hot.
I did purchase one of the expensive fan shrouds in an effort to maximize cooling. When I installed the shroud, the fan was totally located inside of the shroud. I bought a 1/2" spacer to replace the 1 1/4" spacer that is stock, and it positioned the fan pretty close to where it is recommended.
It does appear that the air flow is improved, however, still not optimal. The temperature differential across the radiator is about 35F which is pretty good. I'm still going to work on a few more things. I'll attach some picture to show where the fan is located using a 1/2" spacer. The spacer was from flex a lite and the part number is FLX-836. It took me a while to find the correct spacer. This may be some good information for anyone that bought an aftermarket shroud.
